Along with the NRA, AIPAC, has to be one of the heavyweights of the congressional lobbying world. Earlier this week AIPAC announced its enthusiastic support for a US intervention in Syria on their website:
AIPAC News Hub
AIPAC urges Congress to grant the President the authority he has requested to protect America’s national security interests and dissuade the Syrian regime's further use of unconventional weapons. The civilized world cannot tolerate the use of these barbaric weapons, particularly against an innocent civilian population including hundreds of children.
Simply put, barbarism on a mass scale must not be given a free pass.
This is a critical moment when America must also send a forceful message of resolve to Iran and Hezbollah -- both of whom have provided direct and extensive military support to Assad. The Syrian regime and its Iranian ally have repeatedly demonstrated that they will not respect civilized norms. That is why America must act, and why we must prevent further proliferation of unconventional weapons in this region.
America's allies and adversaries are closely watching the outcome of this momentous vote. This critical decision comes at a time when Iran is racing toward obtaining nuclear capability. Failure to approve this resolution would weaken our country's credibility to prevent the use and proliferation of unconventional weapons and thereby greatly endanger our country’s security and interests and those of our regional allies. AIPAC maintains that it is imperative to adopt the resolution to authorize the use of force, and take a firm stand that the world’s most dangerous regimes cannot obtain and use the most dangerous weapons.
AIPAC's support for a US intervention in Syria will go far beyond an announcement a piece from Politico made clear yesterday.
AIPAC to go all-out on Syria
By MANU RAJU
The powerful pro-Israel lobby AIPAC is planning to launch a major lobbying campaign to push wayward lawmakers to back the resolution authorizing U.S. strikes against Syria, sources said Thursday.
Officials say that some 250 Jewish leaders and AIPAC activists will storm the halls on Capitol Hill beginning next week to persuade lawmakers that Congress must adopt the resolution or risk emboldening Iran’s efforts to build a nuclear weapon. They are expected to lobby virtually every member of Congress, arguing that “barbarism” by the Assad regime cannot be tolerated, and that failing to act would “send a message” to Tehran that the U.S. won’t stand up to hostile countries’ efforts to develop weapons of mass destruction, according to a source with the group.
...the stepped-up involvement comes at a welcome time for the White House, which is struggling to muster the votes in both chambers for a resolution that would give President Barack Obama the authority to engage in “limited” military action in Syria for 60 days, with one 30-day extension possible. The hawkish group also has ties to many Republicans, including ones who have been critical of the Obama administration’s handling of U.S.-Israeli affairs.
The top two Senate GOP leaders — Minority Leader Mitch McConnell of Kentucky and Minority Whip John Cornyn of Texas — both have already been urged by top Jewish donors and AIPAC allies to back the Syria resolution, sources say.
So if we're going to stop this intervention in Syria its up to all of us to join together to make so mighty a chorus we can drown out the 800 pound Gorillas and the Beltway Consensus Talking Heads.
As far as who might be most likely to support a Syrian intervention in the House I'd look at the same Congress Critters who voted to against NSA Reforms (134 Republicans and 83 Democrats).
